Try TvRepairKits.com. I just ordered one, I have that same model TV and it is the same problem. I will try to fix it myself as opposed to an expensive service call for repair.

How to reset nokia mobiles life timer to ''0''


Nokia life timer is a counter that keeps track of the Total call time of your phone. It will show how much the phone has been used, and it?s the best thing to check if you?re planning to buy a used Nokia Mobile.
To see the Total Call Time or the life timer counter, On the standby screen type the following code *#92702689# (Easy way to remember this is ? *#war0anty#). And it will pop up a message that shows the life timer in hours and minutes.

Here is a detailed procedure to make this life timer zero.


REQUIREMENTS:
The following files are required to reset the life timer:
  1. Nemesis service suite link: Download from Here
  2. lifetimer.pm file: Download Here
PROCEDURE:
1. Download and Extract the lifetimer.pm file, and Download Nemesis Service Suite.

2. Install Nemesis Service Suite on your Computer, It won?t take much time.(select the first option)

3. Install Nokia Cable Drivers (No need to install, if you have Nokia PC Suite already installed)

4. Connect The Phone in ?PC Suite? Mode to the PC

5. Open Nemesis Service Software

6. Click on ?Scan for new Device? Button on Top right Corner 



7. It Will take a few seconds to scan, and it will load up the software interface after communicating with the Phone.

8. Click the ?Phone Info? Button.


9. On the Bottom, Select and open the ?Permanent Memory? Tab, which is next to the Fbus info.


10. Click the ?Write? button on Below right, and open the Extracted lifetimer.pm file on your PC. 


11. After the lifetimer.pm file is opened , it will immediately start writing it to the Phone?s EEPROM Area.




12. The Procedure will end when the progress bar reaches 20%. This is normal , and on the bottom right side, it will display its done.

13. Unplug the Phone, and Restart it.

14. After boot up, Check the life timer .


Note: This method has been tested on following devices: Nokia 6630, 6670, 6680, 5500 sport, 5700XM, 6110 Navigator, 6120 Classic, N70, N72, N73,N76, E50, E51, E61i, E65, N80, N91, N95, N95 8GB, 5800XM Mobile devices. If you want to try it on other S60v3 or S60v5 mobiles, do it at your own risk.


Caution:
  • Power Failure During Writing will cause damage to the Phone, And there is a chance that it might brick the phone as well.
  • Loose, worn out Data Cables Might fail the Writing process, and there are chances of damage to the EEPROM area of the phone.
  • Do not attempt this with phones that are not included in the confirmed list.

Hi Sandy, the problem with your TV is called "convergence". It can be a problem with the convergence board or more likely in this model in the power supply or deflection circuits. Unfortunately, troubleshooting by a technician is required.

Problem with objective lens


This is an air separated doublet (invented in the 1700s). Each lens element is made of a different type of glass to reduce false color. So if you get it back together wrong you will notice the bad image. Look at the edges of the elements the thinner one usually goes in front. The concave surface of the rear element should also face front. With the plastic separation ring in place the convex surface of the front element should not come into contact with the rear element's concave surface. It shouldn't rock, there should be about 1mm air separation between them. On shorter focal length refractors (under 500mm) the front surface of the front element has less concavity that the rear surface. On longer focal lengths they are about the same. All I can say is try this and if the image isn't that great flip the front element and try it that way. And don't feel too bad we've all learned the hard way to mark the edges of the elements as we take them out. HTH
